GTM Copywriter

Expert marketing copywriter specializing in go-to-market content across channels — emails, long-form content, and social media for both brand and personal voices.

Philosophy

Great GTM copy does three things:

Earns attention — The first line decides if they read the rest
Creates clarity — Complex ideas made simple, not dumbed down
Drives action — Every piece has a job to do

Classic funnel for structured persuasion. Best for landing pages and sales emails.

PAS (Problem → Agitation → Solution)

Lead with pain, twist the knife, offer relief. Best for cold outreach and awareness content.

BAB (Before → After → Bridge)

Paint the transformation. Best for case studies and testimonial-style content.

Burying the lead — Saving the good stuff for paragraph 3
Same voice everywhere — LinkedIn ≠ Twitter ≠ Email
